BACKGROUND OF THE INVENTION

The present invention relates to the field of genes encoding ion channels, and the proteins encoded thereby, and more particularly to genes related to the human Erg gene.

A family of genes that encode potassium ion channel proteins have been identified in and isolated from, various organisms including C, elegans, Drosophila, mouse, rat, and humans. The members of the gene family are classified into subfamilies (eag, elk, and erg) on the basis of sequence similarity. The Eag family is named for the original isolate from Drosophila (ether-a go-go or eag). The Elk family includes genes that encode eag-like potassium ion channels. The Erg family includes eag-related genes.

Typically there is about 40-50% amino acid identity among proteins in the different subfamilies. Within a subfamily, the amino acid identity is about 60-70% even for proteins from different species. The human Erg ion-channel gene (Herg) corresponds to the LQT-2 genetic locus and maps to chromosome 7 q-35-36. Mutations in Herg can cause long-QT (LQT) syndrome, a relatively rare disorder that causes syncope and sudden death due to ventricular arrhythmia. The characteristic increased electrocardiographic Q-T interval evidences delayed repolarization of the cardiac action potential. At a molecular level, the delayed repolarization is linked with abnormal ion channel behavior. The Herg gene, in particular, is shown to be altered or defective in both acquired and inherited forms of LQT syndrome.

Herg ion channels are inwardly rectifying potassium channels. Herg channels have properties consistent with the gating properties of eag, and other, outwardly-rectifying, S4-containing potassium channels, but with the addition of an inactivation mechanism that attenuates potassium efflux during depolarization. It is thought that these properties of Herg channel function are critical to maintaining normal cardiac rhythmicity. The molecular mechanism by which Herg ion channels protect the heart against inappropriate rhythmicity is elucidated in Smith, P. L., et al., "The Inward Rectification Mechanism of the HERG Cardiac Potassium Channel," 379Nature 33 (1996) and in Miller, C. "The Inconstancy of the Human Heart," 379 Nature 767 (1996).

The Herg gene that encodes the Herg potassium ion channel subunits was described by Warmke, J. W. and B. Ganetzky, "A Family of Potassium Channel Genes Related to eag in Drosophila and Mammals," 91 PNAS USA 3438-3442 (1994), incorporated herein by reference. The Herg DNA sequence is found at Genbank Accession Number U04270. A Drosophila erg gene was described by Titus, S.A., et al., "The Drosophila erg K⁺ Channel Polypeptide Is Encoded by the Seizure Locus," 17 J. Neuroscience 875-881 (1997) and is reported at Genbank Accession Number U42204. A C. elegans erg gene is found at Accession Numbers U02425 and U02453 of the Genbank database. The two 10 kb pieces of genomic DNA therein disclosed encode amino acid sequences that align respectively to the N- and C-terminal halves of the Drosophila erg polypeptide.

Because of the critical role played by the Herg gene in a well known human disease, and its use in the development of pharmacological therapies, it is important to determine whether additional Herg-like genes exist in humans that could also play an important role in LQT syndrome or in other diseases characteristic of abnormal ion channel function. Herg channels are also an important target for the development of new pharmaceuticals.

BRIEF SUMMARY OF THE INVENTION

The present invention is summarized in that novel genes disclosed herein encode Herg-type potassium channel proteins. Because of this similarity to Herg, (85% amino acid identity in the protein core) some or all of these genes will likely play an important physiological role in humans. Consequently, the genes have utility for genetic screening and gene therapy applications. Additionally, the potassium ion channels encoded by the genes can be important targets for developing new pharmaceuticals and for testing the specificity of pharmaceuticals for which Herg is the intended target. The novel gene sequences can also be used to identify corresponding genes in other clinically relevant organisms, such as rats and mice for developing animal models and test systems to evaluate the physiological function of normal and abnormal ion channels. Such models can also be used to evaluate drug therapies.

It is an object of the present invention to provide two novel human genes related to Herg.

Other objects, advantages, and features of the present invention will become apparent upon consideration of the following detailed description.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

FIG. 1B shows an alignment of Herg with rERG 6.1 and with two dbESTs having similarity to rERG 6.1. FIG. 1C shows a strategy for determining the nucleotide sequence of clone 11.1 that encodes Herg-2.

FIG. 2 depicts a comparison of the amino acid sequences of Herg (SEQ ID NO:13), Herg-2 (SEQ ID NO:2) and Herg-3 (SEQ ID NO:4) coding sequences. Sequences enclosed in a box are identical in two or three of the compared sequences.

DETAILED DESCRIPTION OF THE INVENTION

A plurality of DNA sequences that encode Herg-type potassium ion channels are disclosed. A DNA sequence herein identified as Herg-2 is shown in SEQ ID NO:1. The amino acid sequence predicted from the Herg-2 cDNA sequence is shown in SEQ ID NO:2 A DNA sequence herein identified as Herg-3 is shown in SEQ ID NO:3. The amino acid sequence predicted from the Herg-3 cDNA sequence is shown in SEQ ID NO:4.

It is noted that the 5' end of the Herg-3 gene is not yet determined. Thus, the nucleotide and amino acid designations are intended to relate solely to the sequence listing presented, but not to the position of nucleotides and amino acids relative to the actual 5' or amino terminus of the Herg-3 gene or protein. Likewise, since an indeterminate number of internal amino acids are missing from both Herg-2, and an indeterminate number of N-terminal amino acids are missing from Herg-3, the reference to amino acid numbers and nucleotide numbers are merely exemplary and are intended to refer only to the nucleotides and amino acids designated herein, rather than to any particular position of the actual proteins or nucleic acids. Accordingly, any claim to a sequence that includes this portion of the gene is intended to encompass any sequence that includes the sequences upstream and downstream of the portion along with the sequences of that portion.

Several interesting aspects of the Herg-2 cDNA and protein are noted. The methionine codon shown as codon 15 of the Herg-2 protein may represent an alternate translation initiation sequence. Also, a section of the protein of approximately 100 amino acids (corresponding to about 300 base pairs of the cDNA sequence) is missing from the reported sequence. The missing bases are positioned just after the methionine-encoding ATG at nucleotide position 1567. The unknown bases are shown as N's in SEQ ID NO:1.

One of ordinary skill can distinguish the Herg-2 gene, and equivalent related genes, from the known Herg gene by virtue of DNA sequence differences. Herg-2 is distinguished from Herg and from Herg-3 in a segment toward the 5' end of the coding region, shown at bases 248-538 of SEQ ID NO:1. This sequence is characteristic of Herg-2 and is not found in either the Herg or Herg-3 gene. These nucleic acid sequences are considered preferred embodiments of the invention. The Herg-2 cDNA sequence can also be described as a sequence that comprises bases 248-1567 (that is, the coding portion of the cDNA up to the missing internal portion of the gene), or as a sequence that comprises bases 248-125 (the coding portion including the sequences upstream and downstream of the missing portion, as well as the missing portion itself). These sequences correspond to amino acids 1-97, 1-440, and 1-626 of the polypeptide encoded by the cDNA, respectively.

Likewise, the Herg-3 gene can also be distinguished from the Herg and Herg-2 genes by virtue of sequences located close to the 3' end of the cDNA and the corresponding polypeptide. Specifically, a sequence that characterizes the Herg-3 is shown between bases 2335 and 2616 of SEQ ID NO:3. This is considered a preferred embodiment of the invention. Other embodiments include a DNA molecule that includes a sequence of nucleotides as shown between bases 1561 and 2616 of SEQ ID NO:3, or a DNA molecule that includes a sequence of nucleotides as shown between bases 34 and 2616 of SEQ ID NO:3. Those nucleotides correspond to amino acids 768-861, 510-861 and 1-861 of the protein encoded by the Herg-3 cDNA (SEQ ID NO:4). Again, these sequences are not found in either Herg or Herg-2 and are considered to be characteristic of Herg-3.

It is noted that the invention is intended to cover all forms of the genes disclosed herein, including, for example, the genes in cDNA form or in genomic (unspliced) configuration.

Of course, one skilled in the art will appreciate that the characteristic sequences need not be identical at the DNA or the protein levels to those presented herein. Through the ordinary course of evolutionary mutation and somatic change in individuals, certain nucleotide and/or amino acid substitutions and small additions or deletions not affecting the activity of the proteins encoded thereby are to be expected. Specifically, it is also known that the degeneracy of the genetic code permits "wobble" at the third bases of codons. Thus, some nucleotide changes will have no bearing at all on the amino acids encoded by the genes. The applicants intend that the claims encompass all such modifications and variations of the sequences presented, without regard to the species of origin of the gene or protein or indeed whether isolated from a living organism or deliberately engineered in vitro using recombinant DNA methods available to the genetic engineer.

One skilled in the art will readily appreciate that, being in possession of sequences for Herg-2 and Herg-3, it is now possible to probe the genetic material of other animal species, including, but not limited to, mammals, rodents, nematodes, and the like.

Genetic probes targeted to the characteristic areas of the genes can be employed in much the same way that the Herg gene sequences were employed to obtain and isolate additional novel gene sequences.

Once in the possession of one of these novel genes, or an equivalent gene, one can insert the gene into an appropriate expression vector in order to obtain functional expression of the encoded channel polypeptides in a heterologous system. Such procedures are used to characterize the functional properties of the channels and to evaluate them as targets for pharmaceuticals. In addition, the channel polypeptides can be overproduced in a suitable host cell and then purified from the other cell proteins using methods available to those skilled in the art.

Among the known methods for expressing potassium channel genes, two ways are most often employed in the art: expression in a Xenopus oocyte system and expression in cultured mammalian cells. For the first method, a cDNA encoding the open reading frame of Herg-2 or Herg-3 or portions thereof can be incorporated into commercially available bacterial expression plasmids such as the pGEM (Promega) or pBluescript (Stratagene) vectors or one of their derivatives. After amplifying the expression plasmid in bacterial (E. Coli) cells the DNA is purified by standard methods. The incorporated potassium channel sequences in the plasmid DNA are then transcribed in vitro according to standard protocols. The RNA thus prepared is injected into Xenopus oocytes where it is translated and the resulting channel polypeptides are incorporated into the plasma membrane. The functional properties of these channels can then be investigated by electrophysiological, biochemical, pharmacological, and related methods. All the necessary procedures for functional expression of channels in Xenopus oocytes have been previously described in the literature and are well-known to one skilled in the art (Iverson, L. E., et al., "A-type potassium channels expressed from Shaker locus cDNA," Proc. Natl. Acad. Sci. USA 85:5723-5727 (1988); Timpe, L. C., et al., "Expression of functional potassium channels from Shaker cDNA in Xenopus oocytes," Nature 331:143-145 (1988); Root, M. J. and R. MacKinnon, "Identification of an external divalent cation-binding site in the pore of a cGMP-activated channel," Neuron 11:459-466 (1993), all of which are incorporated herein by reference in their entirety).

For the second method, a cDNA encoding the open reading frame of Herg-2 or Herg-3 or portions thereof can be incorporated into commercially available mammalian expression vectors such as the pcDNA series (Invitrogen) or equivalent vectors such as the GW1-CMV vector (British Biotech) or modifications thereof. The resulting constructs can then be transfected into any of several cultured mammalian cell lines such as HEK 293 cells, COS cells, etc. for stable or transient expression in the host cells. The transfected gene sequence is transcribed and translated by the host cells and the resulting channels are incorporated into the plasma membrane. The properties of these channels can then be investigated by electrophysiological techniques, binding studies, pharmacological assays, and similar methodologies. The protocols for obtaining expression of ion channels in mammalian cells is well-described in the literature and known to be those skilled in the art (Choi, K. L., et al., "Tetraethylammonium blockade distinguishes two inactivation mechanisms in voltage-activated K⁺ channels," Proc. Natl. Acad. Sci. USA 88:5092-5095 (1991); Jurman M. E., et al., "Visual identification of individual transfected cells for electrophysiology using antibody coated beads," Biotechniques 17:876-881 (1994); Smith, P. L., et al., "The inward rectification mechanism of the HERG cardiac potassium channel," Nature 379:833-836 (1996); Stansfield, C. E., et al., "Elevation of intracellular calcium by muscarinic receptor activation induces a block of voltage-activated rat either a-go-go channels in a stably transfected cell line," Proc. Natl. Acad. Sci. USA 9910-9914 (1996), all of which are incorporated herein by reference in their entirety).

The following examples describe the isolation of Herg-2 and Herg-3. They are intended to be exemplary and not limiting on the scope of the invention. The same method may be used to isolate additional Herg-related genes.

By providing the characteristic cDNA and polypeptide sequences of additional members of the Herg subfamily, the inventors enable one to screen human and non-human animal subjects for the presence of normal and mutant forms of the Herg-2 and Herg-3 genes and polypeptide in human and non-human animals. Monoclonal or polyclonal antibodies directed against epitopes unique to Herg-2 or Herg-3 ion channels can now be produced using standard methods. Such antibodies could be used to monitor the role of potassium ion channels in normal or diseased subjects, although the shortcomings of antibody analysis have been noted above. To be useful, the antibodies would need to be non-cross-reactive with other proteins.

Herg-2 and Herg-3 appear to be active genes that are likely to encode an ion channel protein that can participate in disease processes of the type known to involve the Herg ion channels. It may be necessary to modulate the Herg-2 or Herg-3 ion channel activity to treat such a disease state, either by increasing or decreasing the activity. This can be accomplished by targeting pharmaceuticals to the protein encoded by Herg-2 or Herg-3. It will also be necessary to consider the physiological effect on those gene products on any treatment that modulates the activity of Herg ion channels.

In addition, it will also be possible to identify specific nucleotide or amino acid lesions that modulate Herg, Herg-2, or Herg-3 function. By modifying the Herg-2 or Herg-3 gene sequence, it will now be possible to develop genetic therapies for reversing the effects of such lesions, by replacing aberrant Herg-2 or Herg-3 genes with non-aberrant versions.

Moreover, even substitution of one amino acid for another, or additions or deletions of several amino acids may have little or no functional effect upon the protein encoded. The invention is intended to cover such variation as one skilled in the art would expect to find in such a gene or protein, whether such variation derives from natural variation among individuals or by deliberately introducing modification.

The invention will be more fully understood by considering the following examples, which are intended to be exemplary and not limiting on the scope of the invention.

EXAMPLES

A rat cDNA encoding a possible counterpart of Herg channels was obtained by screening a rat brain cDNA phage library (Stratagene Catalog Number 937502) with a partial Herg cDNA probe of approximately 2000 bases that spanned the segment from nucleotide 260-2300 of the Herg sequence published at Genbank Accession Number U04270. The library was inoculated onto eighteen large plates at a titer of 40,000 pfu/plate according to the manufacturer's instructions. The inoculated plates were then incubated at 37° C. for 14 hours. Phage were lifted from each plate onto nitrocellulose membranes. Phage DNA on the membranes was denatured and fixed to the membranes according to instructions from Stratagene.

The membranes containing the denatured and fixed DNA were incubated with the probe. The cDNA probe was ³² P labeled using a standard protocol for random primed DNA synthesis. After the radiolabelled Herg cDNA probe was denatured by boiling for 5 minutes, the probe (5×10⁷ total CPM) was incubated with the filters for 14 hours at 55° C. under the following hybridization conditions (2% mismatch): 2×SSCP(1×SSCP=120 mM sodium chloride, 15 mM sodium citrate, and 20 mM sodium phosphate), 1×Denhardt's, 0.25 mg salmon sperm DNA, and 0.1% SDS. Hybridization was followed by two washes at 55° C. containing 0.5×SSC and 0.1% SDS.

A single positive hybridizing plaque (Rerg 6.1) was identified and was purified through secondary and tertiary rounds of phage growth and screening with the labeled probe, as above. The rat cDNA contained in this phage clone was purified and its length was determined by gel electrophoresis to be about 2.3 kb. Approximately 1 kb of the 5' end of the rat cDNA was sequenced using the Sequenase 2.0 dideoxy chain termination method (United States Biochemical) and an amino acid sequence was deduced from the cDNA sequence.

About 230 amino acids of the rat gene sequence aligned well with the Herg amino acid sequence in a region spanning the pore segment through the cyclic nucleotide binding domain (cNBD)-like segment of Herg. See FIGS. 1A and 1B. The region of alignment corresponds to amino acids 628 to 864 of Herg. No strong identity was found between the rat and human erg polypeptides beyond this region. However, the rat cDNA resembled the Herg sequence more closely than it did any other known polypeptide in the Eag family.

The rat erg sequence was compared against the dbEST database using the rat erg sequence as the query sequence. The sequence that showed the best match in this search was from a partial human cDNA having a Gen Bank Accession Number H96170. The EST revealed in the Genbank BLAST search was derived from I.M.A.G.E. Consortium (LLNL) Clone ID 232319 (Lawrence Livermore National laboratory, Livermore, Calif.). See Lennon, G. G., et al., "The I.M.A.G.E. Consortium: An Integrated Molecular Analysis of Genomes and Their Expression," 33 Genomics, 151-152 1996. The amino acid sequence that would be encoded by this partial human cDNA had greater similarity with Herg than it did with mammalian Eag or Elk polypeptides. Moreover, this putative polypeptide sequence aligned well with the rat erg sequence in the region beyond the cNBD-like segment where the rat sequence diverged from Herg.

rERG 6.1 also showed similarity to a dbEST cDNA clone having Genbank

Accession Number F02206, which is unavailable for purchase.

The I.M.A.G.E. Consortium clone 232319 was purchased and was used to screen a human genomic library (Stratagene Catalog Number 945203) using the conditions used to screen the rat cDNA library. Eighteen filters, each containing genomic DNA from approximately 40,000 phage clones, were screened. Two phage clones gave positive hybridization signals in the primary screen and hybridized to the cDNA probe in secondary and tertiary screens.

A strategy for obtaining Herg-2 and for determining its nucleotide sequence is shown in FIG. 1. One genomic clone (denoted 11.1) yielded a positive PCR-amplification product under the following conditions:

3' primer 5'-GGAATTCATGTCAATGCCATTGGTG-3' (SEQ ID NO: 5)

5' primer: 5'-TGGHTNGCNTGYATHTGGTA-3' (SEQ ID NO: 6)

Denaturation at 94° C. for one minute

Annealing at 40° C. for two minutes

Extension at 72° C. for four minutes,

for a total of 2 rounds followed by 35 rounds of further amplification as above except with annealing at 48° C. for one minute. The 3' primer was based on bases 91-111 of the sequence of the dbEST clone having the Genbank accession number F02206. The degenerate 5' primer was based on the known S5 sequences (Warmke et al., 1994) of Eag, Meag, Elk, and Herg.

The PCR amplification product (PCR Product Number 1) was about 1.8 kb, by gel electrophoresis. Since the expected size of the open reading frame in this region was about 450 base pairs by comparison with other known Eag family members, the size of the PCR product suggested that the genomic clone contained at least 1 intron. The PCR product was used as a template for DNA sequencing by the dye termination method using an automated sequencer from Applied Biosystems, Inc. The nucleotide sequence at either end of the PCR product was determined using the two PCR amplification primers as sequencing primers. The amplification product was determined to include 5' and 3' open reading frames flanking at least one intron having typical splice donor and splice acceptor sequences. The amino acid sequence of this region aligned well with the Herg sequence in a region spanning the segment from S5 to just beyond S6.

Additional sequence 5' to the S5 segment was obtained from genomic clone 11.1 by PCR amplification using a degenerate 5' primer based on the S1 segments of Eag, Meag, Elk and Herg (5'TGGGACTGGNTNATHYT-3') (SEQ ID NO: 7). The 3' primer was the specific primer for the S6 segment previously specified (SEQ ID NO: 5). The resulting PCR-amplification product (PCR Product Number 2) was approximately 4 kb in size. This product was used as a template for yet another PCR reaction using the same 5' primer and a 3' primer based on the sequence obtained from the 5' end of PCR Product Number 1 (5'CCTGCACCGAGGGGCCCGAGGCTGGG-3') (SEQ ID NO: 8). The PCR product of this third amplification (PCR Product Number 3) was about 2 kb in size and was sequenced as above. Again, the PCR amplification primers were used as sequencing primers. The 5' end of PCR Product Number 3 included a 260 base pair contiguous open reading frame preceding an intron splice donor site. A 230base pair open reading frame was detected at the 3' end of PCR Product Number 3. The open reading frame sequences at the two ends of PCR Product Number 3 were connected (assuming a single 1500 base pair intron therebetween).

The 163 amino acid sequence encoded by the fragment aligned well with the Herg sequence in a region spanning the segment from S1 through S5.

DNA from genomic clone 11.1 was purified, digested with BamHI and separated by size. The five resulting bands total approximately 18 kb in length. The restriction fragments were transferred to a nylon filter by the Southern Blot procedure. The filter was then hybridized with a radioactive probe representing the 5' end of the Herg cDNA from nucleotide position 1 to 1444 of the published sequence. A single 1.2 kb restriction fragment showed positive hybridization. This band was subsequently isolated and subcloned into a pBlueScript vector. This cloned fragment was sequenced using vector-specific primers. The resulting sequence contained a complete open reading frame that extended from the S1 segment toward the amino terminus until an initiating methionine residue was reached.

I.M.A.G.E. Consortium cDNA Clone ID 232319 was also sequenced using vector-specific primers and several additional sequence-specific primers. A 252 base pair open reading frame at the 5' end of the clone precedes an untranslated segment of about 1 kb. The open reading frame encodes an amino acid sequence that spans the distal third of the cNBD-like segment through the carboxyl terminus. A composite amino acid sequence obtained from human genomic clone 11.1 and I.M.A.G.E. cDNA Clone ID 232319 represents a complete polypeptide sequence, with the exception of an inferred gap of about 100 amino acids between the end of S6 and the distal third of the cNBD-like segment.

The alignment of this polypeptide sequence with other members of the Erg subfamily as well as the position of introns in the Herg-2genomic DNA clearly indicated that it represents not just an alternative splice variant of Herg, but rather a novel member of this subfamily in humans. Importantly, despite the close similarity with Herg, the two polypeptides are not identical. Therefore, the gene and polypeptide described here represents a second member of the erg subfamily in humans, dubbed Herg-2.

A third member of the erg subfamily in humans was obtained by screening a human brain cDNA library using two probes derived from the previously isolated Herg and Herg-2 cDNAs, as follows. The probes were obtained by PCR amplification. A 1515 bp fragment spanning bases 1165 to 2680 of the Herg sequence was obtained by PCR amplification of Herg using 5' primer sequence 5'-ACCATCCTGCATTACAGC-3' (SEQ ID NO:9) and 3' primer sequence 5'-GGCTGCTCCGTGTCCTTG-3' (SEQ ID NO:10). A 630 bp fragment spanning bases 270 to 900 of the Herg-2 sequence was obtained by PCR amplification of Herg-2 using 3' primer sequence 5'-CCCTTGAAGTAGTGGACG-3' (SEQ ID NO:11) and 5' primer sequence 5'-GTGAGCATCAAACCTGGTGTCGCTATG-3' (SEQ ID NO:12). The amplified fragments were radioactively labeled as described previously.

A mixed probe containing both Herg and Herg-2 labeled fragments was used to screen a commercial human brain cDNA library (Clonetech catalogue number HL3002a). The library was plated and screened as described, supra, at a titer of 60,000 pfu/plate. Twenty-four plates were screened in total.

Positively hybridizing plaques were purified through secondary and tertiary rounds of phage growth and screening with the labeled probe as described. Approximately 500 base pairs of DNA sequence from each purified positively hybridizing phage clone were determined by the dye termination method using an automated sequencer from Applied Biosystems, Inc. Among 28 positively hybridizing clones thus analyzed, 6 encoded an amino acid sequence related to that of Herg and Herg-2 but clearly different from either previously identified member of this subfamily.

The complete 3 kilobase long nucleotide sequence of one clone, identified as 13B, containing a 3 kb insert, was determined. The open reading frame is complete from the first membrane-spanning region through the carboxy terminus. The sequence of the amino terminal end of the encoded polypeptide is still incomplete. A second overlapping cDNA, identified as clone 4D, should contain the missing sequence. On the basis of amino acid alignments with Herg and Herg-2 (see FIG. 2) the newly isolated cDNA clearly represents a third member of the Herg subfamily in humans, designated Herg-3. The present invention is not intended to be limited to the exemplified embodiment, but to encompass all such modifications and variations as come within the scope of the following claims.
